Lakewood Instruments uses the latest technology in pH, ORP, and conductivity sensor construction to provide reliable and rugged assemblies for waste water and process water applications. These are used in environmental monitoring and other industries. Lakewood Instruments manufactures reliable, durable and easy to use water treatment controllers that measure the pH, ORP and Conductivity of water, as well as feed chemicals using various schemes. Lakewood Instruments controllers are used in many different applications from cooling towers to boilers to waste water and process applications.
	Cooling Tower Controllers Lakewood Instruments manufactures a full line of pH, Conductivity, and/or  ORP controllers for use in cooling tower applications.  Their cooling tower controllers are divided into low end, mid range, and high end categories.  The model 140 is the simplest, reliable and cost effective conductivity controller series. The model 1500 series, which includes the 1575e, the model 1520/30e and the Model 1512 Conductivity and pH combo controller (or Cond and ORP version) is theirr mid-priced, feature loaded line. The 2000 Series are the expandable and remote communications based controllers for pH, Conductivity and/or ORP applications.
	Boiler Controllers Lakewood Instruments manufactures a full line of boiler conductivity, condensate pH, and condensate conductivity controllers.  The model 1575e can be used for either boiler conductivity or condensate conductivity control.  The model 267 is a basic condensate conductivity controller.  The model 1520e is their condensate pH controller.  The model 2250 is a single boiler conductivity controller and the model 2255 is a multiple boiler conductivity controller.
	Process Controllers Lakewood Instruments manufactures controllers that measure pH, Conductivity, and/or ORP in process applications.  The model 2175P is a conductivity controller, the model 2330P is an ORP controller, the model 2350P is a pH controller, the model 2412P is a pH and conductivity controller, the model 2430P is an ORP and Conductivity controller, the model 2450 is a pH or ORP and conductivity monitor for reverse osmosis applications, and the model 491-495 VersaMeter series are flow totalizers and flow rate indicators.
	Waste Water Controllers    Lakewood Instruments manufactures a full line of pH controllers and sensor for waste water applications.  The model 1520e and the model 2350P controllers can be used with our 520 Series of pH sensors for long lasting and accurate control.
	Process Sensors Lakewood Instruments manufactures a full line of pH, Conductivity, and ORP sensors for process applications.  The Model 520 Series are pH sensors, the Model 530 Series are ORP sensors, the Model 540 Series are very Low Range Conductivity sensors, and the Model 543 Series are Low, Medium, and High Range Conductivity sensors.
